Figure32showsanexampleofapartitionwithtwoFibreChanneldrives
providingtheroboticcontrolpath.LUN1onthedrivesprovidesthe
roboticcontrolpathoverwhichthecommandstotheroboticsarereceived
fromthehost.
Control Path Through a RIM or F-QIP
InaRIM‐orF‐QIP‐basedconfiguration,aRIMoranF‐QIPistheexporting
controllerforthepartition.Thiscontrollerprovidesthebridgebetweenthe
externalFibreChannelinterfacefromthehostandtheinternalinterface
usedbythelibrarytocommunicatewiththerobotics.
ARIMorF‐QIPcansupportuptoeightpartitions;aRIM2cansupportup
to16partitions.Eachpartitionhasfullcontroloftherobotics.Forexample,
ifthelibrarycontainstwopartitions,asingleRIMcanprovidetherobotic
controlpathforbothpartitions.
